The acronym "BASE" was coined by film-maker Carl Boenish , his wife Jean Boenish, Phil Smith, and Phil Mayfield. Carl was the real catalyst behind modern BASE jumping, and in 1978 filmed the first BASE jumps (from El Capitan , in Yosemite National Park ) to be made using ram-air parachutes and the freefall tracking technique. While BASE jumps had been made prior to that time, the El Capitan activity was the effective birth of what is now called BASE jumping. BASE jumping is significantly more dangerous than similar sports such as skydiving from aircraft, and is currently regarded by many as a fringe extreme sport or stunt BASE numbers are awarded to those who have made at least one jump from each of the four categories. When Phil Smith and Phil Mayfield jumped together from a Houston skyscraper on January 18th, 1981, they became the first to attain the exclusive BASE numbers (BASE #1 and #2, respectively), having already jumped from antennae, spans, and earthen objects. Jean and Carl Boenish qualified for BASE numbers 3 and 4 soon after. A separate "award" was soon enacted for Night BASE jumping when Mayfield completed each category at night, becoming Night BASE #1, with Smith qualifying a few weeks later.

Two Base Jumpers jump from a bridge and are connected each-other by a bungee chord. When they are both under canopy one jumper cuts away his main parachute and bungee jumps from the other BASE jumper. He then cuts away the bungee chord and pulls a reserve parachute which slows him down just enough to land in a tree and not die. Amazing! Tags: bungeeExtremejumpsplaneSocial: BookmarkPermalink

BASE jumping

From Wikipedia, the free encyclopedia.

BASE jumping is the sport of using a parachute to jump from fixed objects. 'BASE' is an acronym that stands for the four categories of objects from which one can jump; (B) uilding, (A) ntenna (an uninhabited tower such as an aerial mast), (S) pan (a bridge, arch or dome), and (E) arth (a cliff or other natural formation). BASE jumping is much more dangerous than skydiving from aircraft and is currently regarded as a fringe extreme sport.

History

Equipment and Techniques

BASE jumping grew out of skydiving (recreational parachuting from aircraft). There are three main technical differences between the two. Firstly, BASE jumps are generally made from much lower altitudes than skydives. Secondly, a BASE jump takes place in close proximity to the cliff or tower which provided the jump platform. Thirdly, the BASE jumper generally has a lower airspeed than a skydiver throughout the jump, because a BASE jump starts with zero airspeed, and (due to the limited altitude) a BASE jumper very seldom approaches the terminal velocity (airspeed) of a skydiver. All three factors have significant implications. Firstly, the BASE parachute system has to be made to open very quickly at low airspeeds. Skydiving parachutes are reefed to slow down the opening and reduce opening shock forces. Secondly, the cliff or tower presents a risk to the BASE jumper if, for example, the parachute opens facing backwards. An off-heading opening is not considered a problem in skydiving, but has caused fatal impact injuries in BASE jumping. However, it is the low altitude which usually presents the greatest risk.
